1 | kmod 21 |
2 | ======= | |
3 | ||
4 | - New features: | |
5 | - kmod tool started to learn the "insert" and "remove" commands that | |
6 | are the simplified versions of the older modprobe tool. These | |
7 | commands are still work in progress so they are hidden behind a | |
8 | --enable-experimental flag during build. It should not be enabled | |
9 | unless you know what you're doing. | |
10 | - kmod tool now prints the relevant configuration options it was built | |
11 | with when the "--version" argument is passed. This helps to mitigate | |
12 | problems for example when the user is trying to load a compressed | |
13 | module but kmod was built without support for the compression method. | |
14 | ||
15 | - Improvements to testsuite: | |
16 | - Cache built modules so it is easier to run "make check" on build | |
17 | servers by distro maintainers. If kmod is configured with | |
18 | --disable-test-modules the modules from cache will be used by | |
19 | "make check". No changes to the tests are needed and all of them | |
20 | can run fine. | |

22 | kmod 20 |
23 | ======= | |
24 | - Bug fixes: | |
25 | - Handle bogus values from ELF, making sure they don't overflow while | |
26 | parsing the file | |
27 | - Fix leak in depmod when -b flag is passed multiple times | |
28 | - Multiple minor fixes from static analysis by coverity and | |
29 | clang-analyze | |
30 | - Fix race between loading modules and checking if it's loaded in the | |
31 | kernel | |
32 | ||
33 | - New features: | |
34 | - There's a change in behavior regarding builtin modules: we now only | |
35 | consider as builtin those that are present in modules.builtin index. | |
36 | Previously we were also checking the presence of | |
37 | /sys/module/<module-name>, but this is racy and only modules that | |
38 | contain parameters are the ones creating a directory in sysfs. | |
39 | ||
40 | Now some commands will start to fail, e.g. "modprobe vt". Since vt | |
41 | can't be compiled as a module it's not present in modules.builtin | |
42 | index. Previously we would report at as builtin, but now we fail | |
43 | because we couldn't find the module. | |
44 | ||
45 | - Improvements: | |
46 | - Integration of gcov into the build. Currently libkmod is at ~70% | |
47 | covered and tools at ~50% by tests in the testsuite. Utility | |
48 | functions and structures in shared have more than 90% of coverage. | |
49 | - Upload build to coverity | |
50 | ||
51 | - Improvements to testsuite: | |
52 | - Fix parsing return codes of init_module() calls | |
53 | - Add tests for utility functions in shared/ | |
54 | - Add tests for kmod_module_remove_module() | |
55 | - Add playground, in which our own modules are compiled | |
56 | - Port all tests to use modules from module-playground instead of | |
57 | copying prebuilt modules to the repository | |
58 | - Properly handle binaries that exit with no output | |
59 | - Besides comparing the output of commands, allow to copy to | |
60 | stdout/stderr | |

62 | kmod 19 |
63 | ======= | |
64 | ||
65 | - Bug fixes: | |
66 | - Fix missing CLOEXEC in library | |
67 | - Fix error message while opening kmod's index | |
68 | ||
69 | - New features: | |
70 | - Add kmod(8) man page | |
71 | - Allow to build with libc's without be32toh() | |
72 | - Move code around separating common code and data structures into a | |
73 | shared directory. This allows to share more code between library and | |
3b058610 | 74 | tools, making the binary size of tools smaller. |
f9e2167b | 75 | - Clarify tools vs library licenses |
3b058610 | 76 | - static-nodes: when writing in tmpfiles format, indicate that |
f9e2167b LDM |
77 | creation of static nodes should only happen at boot. This is used and |
78 | required by systemd-217+. | |
79 | ||
80 | - Improvements to testsuite: | |
81 | - Add tests for newly created shared/ code | |
82 | - Improve how tests are declared so there's less boilerplate code for | |
83 | each test. | |

85 | kmod 18 |
86 | ======= | |
87 | ||
88 | - Bug fixes: | |
89 | - Fix leaks in error paths | |
90 | - Fix use-after-free in hash implementation causing a wrong index to be | |
91 | generated by depmod with out-of-tree modules | |
92 | ||
93 | - New features: | |
94 | - Calling depmod with modules creating a dependency loop will now make | |
95 | depmod return an error and not update the indexes. This is to protect | |
96 | the current index not being overridden by another index that may cause | |
97 | a boot failure, depending on the buggy module. It's a necessary | |
98 | change in behavior regarding previous kmod releases and | |
99 | module-init-tools. The error message was also improved to output | |
100 | the modules that caused the dependency cycle. | |
101 | ||
102 | - Improvements to testsuite: | |
103 | - Fix and improve expected-fail test | |
104 | - Add tests for hashmap implementation | |
105 | ||
49d8e0b5 LDM |
106 | kmod 17 |
107 | ======= | |
108 | ||
109 | - Bug fixes: | |
110 | - Fix matching a "." in kernel cmdline, making garbage in the command | |
111 | line be parsed as kmod options | |
112 | - Fix man pages to clarify we don't fallback to parsing modules.dep | |
113 | but instead we depend on modules.dep.bin (generated by depmod) to | |
114 | be present | |
115 | - Fix ELF parsing on 32 bit systems assigning the wrong class. | |
116 | - Fix partial matches of search directives in depmod. Previously having | |
117 | a line in depmod.conf such as "search foo foobar built-in" would cause | |
118 | unpretictable results because foo is a partial match of foobar as well. | |
119 | - Fix unaligned access in modinfo when getting the signature from a | |
120 | module | |
121 | - Make sure softdeps are treated as optional dependencies | |
122 | ||
123 | - New features: | |
124 | - Accept special files given to "-C" switch in modprobe. This way it's | |
125 | possible to skip system configuration with "modprobe -C /dev/null" | |
126 | - Do not require xsltproc on released tarballs | |
127 | - Don't use Werror anymore | |
128 | - Add experimental python bindings, merged from python-kmod repository | |
129 | (https://github.com/agrover/python-kmod) | |
130 | - Parse softdeps exported by the kernel as | |
131 | /lib/modules/`uname -r`/modules.softdep | |
132 | ||
133 | - Improvements to testsuite: | |
134 | - Check the list of loaded modules after a test | |

8f67ab53 LDM |
139 | - Bug fixes: |
140 | - Fix usage of readdir_r() | |
36c4bb92 | 141 | - Add some missing checks for memory allocation errors |
8f67ab53 | 142 | |
7ab88044 LDM |
143 | - New features: |
144 | - Remove option from libkmod to allow waiting on module removal if | |
145 | the module is being used. It's dangerous since it can block the | |
146 | caller indefinitely. | |
8f67ab53 LDM |
147 | - Improve compatibility with musl libc |
148 | - Add fallback implementation for compilers without _Static_assert(), | |
149 | e.g. gcc < 4.6 | |
150 | - Minor optimizations to the hash table | |
151 | - Make depmod warn if a module has incorrect devname specification | |
36c4bb92 | 152 | - Use cleanup attribute |
7ab88044 | 153 | |

154 | kmod 15 |
155 | ======= | |
156 | ||
157 | - Bug fixes: | |
158 | - kmod static-nodes doesn't fail if modules.devname isn't available | |
18811d22 LDM |
159 | - Fix getting boolean parameter from kernel cmdline in case the value |
160 | is omitted | |
161 | - Fix some mkdir_p() corner cases (used in testsuite and static-nodes) | |
b3e19ce9 LDM |
162 | |
163 | - New features: | |
164 | - kmod static-nodes creates parent directories if given a -o option | |
18811d22 LDM |
165 | - kmod binary statically links to libkmod - if distro is only interested |
166 | in the kmod tool (for example in an initrd) it can refrain from | |
167 | installing the library | |
168 | - Add shell completion for kmod tool | |
b3e19ce9 | 169 | |
3b38c7fc LDM |
170 | kmod 14 |
171 | ======= | |
172 | ||
173 | - Bug fixes: | |
174 | - Fix some format strings | |
175 | - Protect against NULL being passed around to index | |
176 | - Avoid calling syscall() with -1 when finit_module() is not available, | |
177 | since this doesn't always work | |
178 | - Fix not being able to remove alias due to checking the module's | |
179 | refcount | |
180 | - Minor fixes and refactors | |
181 | ||
182 | - New features: | |
183 | - Improve libkmod documentation, particularly on how flags are dealt | |
184 | with. | |
185 | - Remove ability to build a static libkmod | |
186 | - Add static-nodes command to kmod that parses modules.devname | |
187 | generating output in useful formats | |
188 | ||
abb910eb LDM |
189 | kmod 13 |
190 | ======= | |
191 | ||
192 | - Bug fixes: | |
193 | - Add the long option --symbol-prefix option to depmod (it was absent) | |
194 | and fix its behavior | |
195 | - Don't abort if there's a bogus line in configuration file like "alias | |
196 | psmouse off". Some distros are carrying this since the days of | |
197 | modutils | |
198 | ||
199 | - New features: | |
200 | - Add support for finit_module(2). If the module is load straight from | |
201 | the disk and without compression we use finit_module() syscall when | |
202 | available, falling back to init_module() otherwise | |
203 | - kmod_module_get_info() also returns the signature if the module is | |
204 | signed and modinfo uses it | |
205 | - Use secure_getenv if available | |
206 | - rmmod understands builtin modules, just like modprobe does | |
207 | - Improve compatibility with musl-libc | |
208 | - Test cases exit with success when receiving a signal if they are | |
209 | xfail tests | |
210 | ||
6feba028 LDM |
211 | kmod 12 |
212 | ======= | |
213 | ||
214 | - Bug fixes: | |
215 | - Fix removing vermagic from module when told to force load a module | |
216 | - Fix removing __versions section when told to force load a module: we | |
217 | need to mangle the section header, not the section. | |
218 | - modinfo no longer fails while loading a module from file when path | |
219 | contains ".ko" substring | |
220 | ||

221 | kmod 11 |
222 | ======= | |
223 | ||
224 | - Improvements to testsuite: | |
225 | - Fix testsuite defining symbols twice on 32 bit systems | |
226 | - Allow to check generated files against correct ones | |
227 | ||
228 | - New features: | |
229 | - libkmod now keeps a file opened after the first call to | |
230 | kmod_module_get_{info,versions,symbols,dependency_symbols}. This | |
231 | reduces signficantly the amount of time depmod tool takes to | |
232 | execute. Particularly if compressed modules are used. | |
233 | - Remove --with-rootprefix from build system. It was not a great idea | |
234 | after all and should not be use since it causes more harm then | |
235 | benefits. | |
236 | - Hide --wait option on rmmod. This feature is being targeted for | |
237 | removal from kernel. rmmod still accepts this option, but it's hidden | |
7ab88044 | 238 | now: man page and usage() say nothing about it and if it's used, |
c599606f LDM |
239 | user will get a 10s sleep. This way we can check and help if anyone |
240 | is using this feature. | |
241 | - Refactor message logging on all tools, giving proper prefix, routing | |
242 | everything to syslog when asked for, etc. | |
243 | ||
244 | - Bug fixes: | |
245 | - Fix parsing of modules.order when using compressed modules | |
246 | - Usage messages go to stdout instead of stderr | |
247 | - Fix memory leak in hash implementation | |
248 | ||
40758602 LDM |
249 | kmod 10 |
250 | ======= | |
251 | ||
252 | - New features: | |
253 | - Read coresize from /sys if supported | |
254 | ||
a7fbae03 JE |
255 | - Add flag to kmod_module_probe_insert() to apply blacklisting during |
256 | probe only if mod is an alias. Now modprobe uses this flag by default. | |
40758602 | 257 | This is needed to fix a change in behavior regarding module-init-tools |
a7fbae03 | 258 | and ultimately makes us loading a blacklisted module. |
40758602 LDM |
259 | |
260 | - Better formatting in man pages | |
261 | ||
a7fbae03 | 262 | - Add option to disable building man pages at build time |
40758602 | 263 | |
a7fbae03 | 264 | - Fixes in the testsuite and refactoring of LDPRELOAD'ed libraries |
40758602 LDM |
265 | |
266 | - Re-licensing testsuite as LGPL | |
267 | ||
62081c0f LDM |
268 | kmod 9 |
269 | ====== | |
270 | ||
a7fbae03 | 271 | - Improvements to the testsuite: |
62081c0f LDM |
272 | - Check for correct handling of softdep loops |
273 | - Check for correct handling of install command loops | |
274 | ||
275 | - Bug fixes: | |
276 | - Fix build with compilers that don't support --gc-sections | |
a7fbae03 JE |
277 | - Handle errors when dealing with gzipped modules |
278 | - depmod now handles errors while writing indices, so it doesn't end up | |
279 | with a corrupted index without telling the user | |
62081c0f | 280 | |
46684bc2 LDM |
281 | kmod 8 |
282 | ====== | |
283 | ||
284 | - No new features, small bug fixes only. | |
a7fbae03 | 285 | - Fix a bug in "modprobe -c" output: be compatible with |
46684bc2 LDM |
286 | module-init-tools |
287 | ||
a7fbae03 JE |
288 | - Give a useful error message when init_module fails due to bad |
289 | parameter or unknown symbols | |
46684bc2 LDM |
290 | |
291 | - Fix doc generation | |
292 | ||
8885ced0 LDM |
293 | kmod 7 |
294 | ====== | |
295 | ||
296 | - Re-order dirs for configuration files to match the change in systemd and | |
297 | udev: now the priority is: | |
298 | 1. /etc/modprobe.d | |
299 | 2. /run/modprobe.d | |
300 | 3. /lib/modprobe.d | |
301 | ||
a7fbae03 JE |
302 | - Fix setting CFLAGS/LDFLAGS in build system. This prevented us from not |
303 | allowing the user to set his preferences. | |
8885ced0 LDM |
304 | |
305 | - Bug fixes: | |
306 | - Return same error codes of module-init-tools when removing modules | |
307 | with modprobe | |
308 | - Fix builtin output in "--show-depends" when target kernel is not the | |
309 | same of the running kernel | |
310 | - 'modprobe -r' always look at all command line arguments | |
311 | - Fix '-q' usage in modprobe | |
8885ced0 | 312 | |
26906fe7 LDM |
313 | kmod 6 |
314 | ====== | |
315 | ||
316 | - New API in libkmod: | |
317 | - kmod_module_apply_filter(): a generic function to apply filters in a | |
318 | list of modules. This deprecates the use of | |
319 | kmod_module_get_filtered_blacklist() | |
320 | ||
321 | - More tests in testsuite | |
322 | ||
323 | - Add compatibility with uClibc again | |
324 | ||
325 | - Lookup modules.builtin.bin to decide if a module is built in kernel | |
326 | ||
327 | - Downgrade some log messages so we don't annoy people with useless messages | |
328 | ||
329 | - Bug fixes: | |
330 | - Flag --ignore-loaded was not being properly handled | |
331 | - Infinite loop with softdeps | |
332 | - Infinite loop with dumb user configuration with install commands | |
333 | - Fix leak in index when there's a partial match | |
334 | ||
335 | - Move repository and tarballs to kernel.org | |
336 | ||
e479598b LDM |
337 | kmod 5 |
338 | ====== | |
339 | ||
340 | - Break libkmod's API to insert a module like modprobe does. It now accepts | |
341 | extra an extra argument to print its action and acceptable flags were | |
342 | sanitized. | |
343 | ||
344 | - Share more code between modprobe and libkmod: using the new version of | |
345 | kmod_module_probe_insert_module() it's possible to share a great amount of | |
346 | code between modprobe and libkmod | |
347 | ||
348 | - modprobe no longer works with paths: it only accepts module names and/or | |
349 | aliases now. | |
350 | ||
351 | - testsuite was added to repository, allowing automated tests to be run and | |
352 | easing the way bugs are reproduced. | |
353 | ||
354 | - modprobe: when dumping configuration ('-c' option) separate config | |
355 | and indexes by adding a commented line between them. | |
356 | ||
357 | - Fix bugs wrt normalizing aliases and module names | |
358 | ||
359 | - Fix bug wrt inserting an alias that resolves to multiple modules: we should | |
360 | not stop on the first error, but rather continue to try loading other | |
361 | modules. | |
362 | ||
363 | - Fix unaligned memory access in hash function, causing depmod to output wrong | |
364 | information in ARMv5 | |
365 | ||
366 | - Fix man page build and install: now they are only installed if tools are | |
367 | enabled | |
368 | ||
b53b7e32 LDM |
369 | kmod 4 |
370 | ====== | |
371 | ||
372 | - New APIs in libkmod to: | |
373 | - Get configuration lists: blacklists, install commands, remove | |
374 | commands, aliases, options and softdeps | |
375 | - Dump indexes | |
376 | ||
377 | - Several bugs fixed in libkmod, modprobe, depmod and modinfo | |
378 | ||
379 | - API documentation: if configure with run with --enable-gtk-doc, the API doc | |
380 | will be generated by make. Gtk-doc is required for that. | |
381 | ||
382 | - Man pages are built, which replace man pages from module-init-tools | |
383 | ||
384 | - 'include' and 'config' options in *.conf files were deprecated | |
385 | ||
386 | - configure is not run by autogen.sh. Instead, a common set of options is | |
387 | printed. If you are hacking on kmod, consider using bootstrap-configure | |
388 | script. | |
389 | ||
390 | - 'modprobe -c' works as expected now. As opposed to module-init-tools, it | |
391 | dumps the parsed configuration, not only the file contents. | |
392 | ||
b30a71b8 LDM |
393 | kmod 3 |
394 | ====== | |
395 | ||
396 | - New APIs in libkmod to: | |
397 | - Get symbols from module, parsing the ELF section | |
398 | - Get dependency symbols | |
399 | - Check if resources are still valid or if libkmod must be reloaded | |
400 | - Insert module like modprobe, checking (soft-)dependencies, commands, | |
401 | blacklist. It can run commands by itself and to call a callback | |
402 | function. | |
403 | ||
404 | - Support to load modules compressed with xz | |
405 | ||
406 | - Tools are now bundled together in a single tool called kmod. It can be | |
407 | called using symlinks with the same names as tools from module-init-tools. | |
408 | E.g: /usr/bin/lsmod -> /usr/bin/kmod. With this we are aiming to complete a | |
409 | 1:1 replacement of module-init-tools. | |
410 | ||
411 | - The only missing tool, depmod, was added to kmod together with the necessary | |
412 | APIs in libkmod. | |
413 | ||
414 | - If a program using libkmod runs for a long time, as for example udev, it must | |
415 | check if it doesn't have to re-load libkmod. A new helper function was added | |
416 | in libkmod to check if context is still valid and udev is already using it. | |
417 | ||
418 | - An 'unaligned access' bug was fixed. So those architecture that does not | |
419 | handle unaligned access can use kmod, too. | |
420 | ||
acc18b14 LDM |
421 | kmod 2 |
422 | ====== | |
423 | ||
424 | Some bugs fixed: the worst of them was with an infinite loop when an alias | |
425 | matched more than one module. | |
426 | ||
427 | - New APIs in libkmod to: | |
428 | - Get soft dependencies | |
429 | - Get info from module files parsing ELF | |
430 | - Get modversions from files parsing ELF | |
431 | ||
432 | - Support to load gzipped kernel modules: kmod can be compiled with support to | |
433 | gzipped modules by giving the --enable-zlib flag | |
434 | ||
435 | - Support to forcefully load modules, both vermagic and modversion | |
436 | ||
437 | - Support to force and nowait removal flags | |
438 | ||
439 | - Configuration files are parsed in the same order as modprobe: files are | |
440 | sorted alphabetically (independently of their dir) and files with the same | |
441 | name obey a precedence order | |
442 | ||
443 | - New tool: kmod-modinfo | |
444 | ||
445 | - kmod-modprobe gained several features to be a 1:1 replacement for modprobe. | |
446 | The only missing things are the options '--showconfig' and '-t / -l'. These | |
447 | last ones have been deprecated long ago and they will be removed from | |
448 | modprobe. A lot of effort has been put on kmod-modprobe to ensure it | |
449 | maintains compabitility with modprobe. | |
450 | ||
451 | - linux-modules@vger.kernel.org became the official mailing list for kmod | |
452 | ||
89eba7cb LDM |
453 | kmod 1 |
454 | ====== | |
ecd40ee4 | 455 | |
89eba7cb LDM |
456 | First version of kmod and its library, libkmod. |
457 | ||
458 | In the libkmod it's currently possible to: | |
459 | - List modules currently loaded | |
460 | - Get information about loaded modules such as initstate, refcount, | |
461 | holders, sections, address and size | |
